Corned beef is brisket that has been pickled in spices for days. You can buy it ready-to-cook or corn your own at home, but both are serious sodium bombs, packing more than 500 mg per 3-ounce serving--nearly 25% of the recommended daily limit. For this healthier pressure cooker corned beef and cabbage, we start with a plain brisket and add seasonings ourselves to control the salt level. We also opt for a flat-cut end of brisket, instead of the thicker point cut, as it has less fat, making it easier to slice when cooked. An electric pressure cooker, such as an instant pot, is absolutely key to this recipe, allowing you to cook the brisket in one hour--as opposed to three hours or more in the oven. It also lets you sear and roast in one device, saving cleanup time.
